Forget about herbal medicine. Sharks should be harvested just like any animal species except those proven endangered by credible sources, not from PETA or those piloting the anti-shark-fin movement, the animal rights fanatics. This is a real threat to anybody if sharks, even the plentiful stocks, are totally off limit to regulated harvest. If according to the stats put forth by these animal rights groups, 70 millions sharks are spared annually if shark harvest is stopped, then these hungry sharks will devour anything on their way, including us humans who swim, surf or dive as part of our recreational activities. Can't imagine how anybody will feel safe to go into the water like this poor guy did, even in such shallow water, if hundreds of million of shark are spared and hungry from dwindling food sources due to over-population. But then if you are not the one going into the water, or living near shark infested water, you will probably don't give a damn about the danger people risk. It is just human nature if it is the business of somebody else.
